You are just talking about the output though. If you only think at a "higher level" you aren't doing the actual thinking. Its the same with code. The output may be good enough, but over time you lose touch with the details to the extent that you can no longer serve a useful steering function for the organization. Before coding agents I'd seen this with many humans when they get promoted passed the point where they work with code directly and can't figure out how to add value there.
